VOLMGT_FEATURE_ENABLED(3VOLMGT)VOLMGT_FEATURE_ENABLED(3VOLMGT)NAMEvolmgt_feature_enabled - check whether specific Volume Management fea‐
tures are enabled
SYNOPSIS
cc [ flag ... ] file ... -l volmgt [ library ... ]
#include <volmgt.h>
int volmgt_feature_enabled(char *feat_str);
DESCRIPTION
This function is obsolete. The management of removable media by the
Volume Management feature, including vold, has been replaced by soft‐
ware that supports the Hardware Abstraction Layer (HAL). Programmatic
support for HAL is through the HAL APIs, which are documented on the
HAL web site. See hal(5). The return value of this function is unde‐
fined.
The volmgt_feature_enabled() routine checks whether specific volume
management features are enabled. volmgt_feature_enabled() checks for
the volume management features passed in to it by the feat_str parame‐
ter.
Currently, the only supported feature string that volmgt_fea‐
ture_enabled() checks for is floppy-summit-interfaces. The floppy-
summit-interfaces feature string checks for the presence of the lib‐
volmgt routines volmgt_acquire() and volmgt_release().
RETURN VALUES
The return from this function is undefined.
EXAMPLES
Example 1 A sample of the volmgt_feature_enabled() function.
In the following example, volmgt_feature_enabled() checks whether the
floppy-summit-interfaces feature is enabled.
if (volmgt_feature_enabled("floppy-summit-interfaces")) {
(void) printf("Media Sharing Routines ARE present\n");
} else {
(void) printf("Media Sharing Routines are NOT present\n");
}
